The same review found the seat bulkier than some rivals and potentially cramped in a smaller car's back seat.\nBritax One4Life ClickTight: The preview noted the booster shoulder-belt guide is set into the headrest and that a fully extended headrest is recessed enough to reduce interference with some vehicle headrests.\nCybex Callisto G 360: Two parents used the seat in a Honda CR-V, an Audi A6 sedan, and a Nissan Murano SUV; both said it fit well and took up less space than expected. The reviewer says it is probably too wide for three-across seating, likely too heavy for air travel, and possibly too high for compact cars in booster mode.\nMaxi-Cosi Andi 360° Rotating All-in-One Convertible Car Seat: The walkthrough gives a 19.25 in width and a maximum rear-facing depth of 28.5 in at full recline, and advises measuring because smaller vehicles may not fit it behind the driver.", "kind": "infant/child/booster (all-in-one)", "market": "US", "generated_at": "2026-10-24T21:16:44.420Z", "columns": [ "Fit to vehicle", "Slim design", "Headrest and booster", "Size caution" ], "notices": { "facts": "Every value in the table is a fact RoboTrunk checked, linked to the page it came from.
